Title: Improvements in or relating to the connection of wires, tapes or other metal parts particularly for use in the manufacture of grids for electron discharge devices
IPC: H01J19/00
Filed: 1944-07-11
Abstract: 582,602. Soldering grids of thermionic valves. BROAD, D. A. G. July 11, 1944, No. 13282. [Classes 83 (ii) and 83 (iv)] Metal parts such as wires or tapes, particularly for grids for use in hollow resonators of electron discharge devices, are united to each other at spaced points without the aid of a flux by applying an adhering coating to the parts of a metal of lower melting point and heating the parts in vacuo at such a high temperature below the melting point of the parts so as to cause the spaced points to unite, the heating being continued to remove the coating from the parts intermediate the spaced points. Any excess of coating metal is thus evaporated during the operation. The parts may consist of copper and the coating metal of silver and heating may be effected at a temperature below or above the melting point of the coating metal. The tape or wire may alternatively be of nickel and the coating metal of gold. The coating may be applied by electrodeposition or by rolling. A grid formed by crimping a copper tape 0.001 inch thick provided with a coating of silver 0.0001 inch thick, bending back a straight portion over the apices of the crimps and bending into a flat spiral is united at its contacting points and in the aperture in the copper resonator of the discharge device by placing the coated grid in the aperture, inserting in a vessel which is evacuated by continuous pumping and heated by electric induction at a temperature of about 880‹ to 900‹ C. for one minute. The silver units with the copper to form a eutectic alloy having a melting point of 800‹ to 850‹ C. Specification 286,823, [Class 83 (iv)], is referred to.

Title: Improvements in or relating to heating and ventilating apparatus for use in vehicles
Inventor: COPLEY DONALD WILLIAM
IPC: B60H1/00
Filed: 1961-04-13
Abstract: 1,027,061. Ventilating vehicles. S. SMITH & SONS (ENGLAND) Ltd., and FORD MOTOR CO. Ltd. July 13, 1962 [April 13, 1961], No. 13410/61. Heading F4V. As shown, Figs. 1 and 2, a vehicle heater and ventilator comprises a housing 1 divided into an inlet compartment 2, an outlet compartment 3, and a heating compartment 4 which contains a radiator matrix 9 heated by hot coolant from the vehicle engine, the compartments 2 and 3, 4 and 3, and 2 and 4, being interconnected by ports 6, 7 and 8 respectively. Flap valves 14 and 16 are carried on spindles 15 and 17 respectively, which run between the end walls of the housing 1, valve 14 being movable from a position in which it closes port 6 to a position in which it closes port 8, and valve 15 being movable from a position in which it closes port 7, through an intermediate position in which it lies within, and partially closes, a port 11 in the housing communicating the compartment 3 with the vehicle interior, to a position in which ports 7 and 11 are both unrestricted. Fresh air is forced into the inlet compartment 2 by an electrically driven fan 21, and at least one aperture 12 is provided in the housing to connect the outlet compartment 3 to ducts 13 leading to the inner surface of the vehicle windscreen. The two flap valves are controlled by a single lever, not shown, acting on the spindles 15 and 17 by means of a cam plate and roller followers. In a first position of the lever, air flow between compartments 2 and 3 is entirely prevented. On moving the lever to a second position the valve 14 opens port 6 and closes port 8, giving an unrestricted cool airflow to both the windscreen and the vehicle interior. When the lever is moved from the second position to a third position, valve 16 moves rapidly to the fully open position, while valve 14 moves steadily back until at the third position it closes the port 6 again. Over this second movement, the temperature of air to the vehicle interior rises steadily, while that of air to the windscreen rises only slowly until just before the third position is reached, when it rises rapidly. On moving the lever to a fourth position, the valve 16 moves back to restrict flow through port 11 to the vehicle interior while the bulk of the heated air passes to the windscreen, e.g. for defrosting the latter. In a modification, Fig. 8, the port 6 is replaced by three ports 50 and 52 which open into parts of the outlet compartment leading to the windscreen supply ports 12, and 51 leading to a part of the outlet compartment leading to the port 11, the outlet compartment being divided into three parts by baffles 55 and 56. Wedge-shaped baffles 53 and 54 on the flap valve 14 correspond with the ports 50 and 52 respectively, and, during the movement of the control lever from the second to the third position, restrict the flow of cool air to the windscreen, but not to the vehicle interior, to give a steady temperature rise to the windscreen air flow during this movement.
